The outcome of the fight between turnus and aeneas explains why the language is called latin, but the people are called romans.

If this is a true or false question, I believe the answer is false.
The people are called Romans because of Romulus, not because of Aeneas and Turnus. Romulus and Remus were two brothers who were raised by a wolf and created the beautiful city of Rome. The two of them fought and Romulus killed Remus, so it's based on his name that Rome got its name, and thus Romans were named after the city.

lbs = pounds
